How can I convert decimal fraction to binary in pseudocode and flowchart please?

Question

I would like to know how to develope an algorithm for converting a decimal fraction to binary one in pseudo code and flowchart.

Answer 1

suppose that you have a decimal fraction--0.32 for example

 

Multiply by two; you get 0.64; capture the digit (0 or 1) left of the decimal point, as the first bit after the binary point.

Repeat this step, multiplying by 2, stripping off the new 0 or 1 to make successive binary bits of the binary version. At each step,you will be doubling, and developing a zero or 1 bit. (If you developed a 1 bit units position by multiplying, it gets removed before the next doubling stage)...

 

2(.32) =0.64 gives .0 as first bit of the binary fraction

2).64)=1.28 gives next bit 1, so far we have .01

2(0.28)=0.56 gives next bit 0, so far we have .010

2(.56) gives next bit 1, so far we have .0101

2(.12) gives next bit 0, so far we have .01010

2(.24) gives next bit 0, so far we have .010100

2(48) gives next bit 0, so far we have .0101000

2(.96) gives next bit 1, so far we have .01010001 ... etc. etc.
